BRADFORD: British Labour leader Jeremy Corbyn on Tuesday unveiled a â€œradical and responsibleâ€ manifesto as the party hopes to close the gap against the ruling Conservatives before next monthâ€™s election.

Corbyn, who is flagging badly in the opinion polls, promised to â€œchange our countryâ€ with a raft of proposals including raising taxes on the well-off and renationalising key industries.

Presenting the manifesto in Bradford, northwest England, the Labour leader said the country had been run â€œfor the rich, the elite and the vested interestsâ€ in seven years of Conservative government. â€œIt will lead us through Brexit while putting the preservation of jobs first,â€ he said of the manifesto, appearing in front of Labourâ€™s election slogan: â€œFor the many, not the few.â€

Corbyn promised a Labour government would immediately guarantee the rights of EU citizens in Britain and reject the threat of walking away from Brexit talks.

The manifesto included a tax increase from 40 per cent to 45 per cent for salaries of between 80,000 (94,000 euros, $103,000) and 123,0000 a year, above which there will be a new 50 per cent top rate of income tax. The current 40 per cent tax rate applies to people earning between 45,000 and 150,000.

Labour has said the rise would fund increased investment in the state-run National Health Service (NHS) and would only affect five per cent of earners.

The party also plans a levy on businesses with staff earning large salaries over 330,000.

Labour promised to renationalise the railways, water companies and part of the energy sector in what critics said was a throwback to an era of far greater state intervention in the economy in the 1970s.

Corbyn promised to scrap university tuition fees, a pledge met with huge cheers from supporters gathered to hear him speak at Bradford University.

Labour has also promised it will increase corporation tax to 26 per cent by 2020.

Such changes are among the measures to boost the state coffers by the 48.6 billion needed to meet the commitments outlined in the Labour manifesto.

â€œItâ€™s a programme that will reverse our national priorities to put the interests of the many first,â€ Corbyn said. â€œThis is a programme of hope. The Tory campaign, by contrast, is built on one word: fear.â€

Other pledges in the Labour manifesto include building one million new homes and adding four national holidays to the calendar.

Local Labour campaigner Joe Ashton, 29, said the manifesto set the party apart from others. â€œI think itâ€™s radical without being extreme. Sensible, costed and when tested, our policies are highly popular with the public,â€ he said.

Prime Minister Theresa Mayâ€™s Conservative Party have a double-digit lead over Labour in opinion polls.

But writer Barnaby Neale, a Labour volunteer, said the â€œinspiringâ€ manifesto would sway voters. â€œI wouldnâ€™t be fighting so hard if I didnâ€™t believe Labour has a chance to win, and a very good one,â€ said the 39-year-old.

The Conservatives immediately slammed the plan as â€œnonsensicalâ€ and not properly costed. â€œItâ€™s ordinary working people who will pay for the chaos of Corbyn,â€ Treasury Chief Secretary David Gauke said in a statement.

The director of the Institute for Fiscal Studies, Paul Johnson, said Labourâ€™s tax changes would mark a significant shift.

â€œTax burden already heading upwards. If Labour could raise the 49bn it claims we would have highest tax burden in 70 years,â€ he wrote on Twitter.
